I bought this young Asplenium from a garden centre. The fern was in an area dedicated to terrarium plants with the pot simply labelled as ‘fern mix’. I am uncertain what species or cultivar this fern is – I just know it’s an Asplenium.
As this fern grows and matures it is very likely to outgrow its terrarium, but that’s OK with me – I can enjoy this fern now and move it to a larger enclosure, or grow this fern as a houseplant at a later date.
